Bio Char Vermicomposting Water Flush Toilet System



Theory: Using bio char to assist in the drainage of water from a vermicomposting tank.
Reclaim the drained water and distill it with a solar trough distiller or rocket mass heater when solar is unavailable.

When the sun is available, fuel for the heater could be made via organic matter or local ashei juniper dried in a solar kiln. Human waste gets flushed along with biochar into a holding tank filled with worms. The excess moisture would theoretically flow out of the compost leaving it drained enough for worm colonization, even with multiple flushes (assuming biochar is flushed with the waste).

The biochar can be produced in a tank inside the chimney of a rocket mass heater. This heater can also play host to a plethora of other experiments including the pyrolysis of hydrocarbon waste, casting plastics, and recycling water so that it may effectively be used as a vehicle of disposition while minimizing waste, particularly in the water department. (because it doesn't rain here.)

We will experiment with different ratio of biochar to waste to find an optimal drainage level for worm colonization.

The vermicompost remaining at the bottom of the system can be augered out through a rocket mass heater so the mix is heated to at least 160 degrees in order to kill e.coli .
After that the soil will be tested as a seed starter medium and compared against other vermicompost mixes.

The biochar would in theory absorb nutrients from the waste and urine mix before the worms composted it, assuming the nutrients would not be destroyed by pasteurization, these would add to the effectiveness of the biochar and the growth of the seedlings.

When the time comes where the worms must be harvested for sustainability, these worms must be used in another waste processing system or pasteurized as well (which would kill the worms) to kill e.coli (because e.coli is a big deal.). Pasteurization could be via any method, however solar dehydration would yield dry fish food allowing us to automate feeding in some aquaponics systems.

Men's health states that the average human generates about one pound of waste per day (360 being the average poundage for a years worth of twos.)

Five pounds of waste (five people) could be run on a 10 pound worms system with room to expand in six months.

Since the liquid has to drain through vermicompost and biochar, liquid movements would be caught and filtered before returning to the distillation unit, meaning less blockage.

The toilet water would be condensed back into a toilet flush tank and used to flush more waste and biochar. The water does not leave the system. Urine input would roughly make up the evaporation loss from the process. This would lead to a clean waste processing that yields plants that can be grown out in the aquaponics system. No risk for e.coli. Turning waste into a useable product.
